So I've been having this issue since I started this project. At first I ignored it while working around. All the fittings and air terminals that I have placed are a bit faded out and I cannot press on them. Now when I want to copy this system to the other floors revit only copies the ventilation units ignoring all the other ducts and fittings. I've been trying to solve this by reading millions of threads and couldn't find anything. Maybe i'm overseeing something. I've checked and tried all the visibility settings and so on.
I'm also on a rush to finish and present this project as I am a student and this is my semester project. Please help.
Thanks in advance!
